BB shows emails sent, so does Gmail, but receipients not receiving them.

This is driving me crazy....Anybody have any ideas? It's been going on for a few days now. I've deleted the account off my phone and reinstalled as well as done a battery pull. Any suggestions would be appreciated.

Re: BB shows emails sent, so does Gmail, but receipients not receiving them.

It is my work email address set up through gmail - whenever I send through my work email @xyz.com to another work email address @xyz.com it all looks good (shows sent on phone and through gmail web log-in) but they don't get it. Also doesn't go through if I'm replying to someone. I've checked with our IT department and theyre saying it is something to do with my phone as this isn't happening to anyone else.
